WILLIAM A. KETTENRING, OF DEFIANCE, OHIO.

WOOD-TURNING LATHE.

SPECIFICATION forming part of Letters Application filed June 16, 189.).

To all whom it may concern.-

Be it known that I, WILLIAM A. Kn'rrure RING, of Defiance, county of Defiance, State of Ohio, and a citizen of the United States, have invented an Improved \VoodTurning Machine, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification.

My invention relates to a machine for turn ing wood in the manufacture of neck-yokes, ball-bats, and similar cylindrical articles having variations in diameter or molded projections and depressions; and my invention consists in the combination of devices in such a machine hereinafter particularly specified, and more at length recited in the claims.

Figure 1, Sheet 1, is a front elevation of a machine containing my improvements. Fig. 2, Sheet 1, is a plan of the same. Fig. 3, Sheet 2, is an elevation of one end of thesame. Fig. 4 is an opposite end elevation of the same. Fig. 5is an edge view of the cutter-head. Fig. 6 is a side elevation of the same. Fig. 7 is a side elevation of the tail-block as seen from the rear of the machine, and Fig. 8 is an interior end view of the same.

I will proceed to describe a machine to which my improvements hereinafter described are applicable.

A is the frame of the machine, composed of the end pieces, a, and the cross-piece or trunk a, as shown.

B is the arbor, running in bearings b and driven by pulley b, and on which are mounted the cutter-heads 0. (Shown in Figs. 5 and 6.) In the principal figures of the drawings these cutter-heads are not shown on the arbor; but their arrangement thereon in machines of this class is well known. The knives or cutters (not shown) are bolted to lugs c on the cutterheads in the well-known way. These knives or cutters are in machines of this class set and arranged to cut or turn the strip of wood presented to them so that said strip will be turned with variations in the diameter of the cylinder produced and with molded projections or depressions. The direction of rotation of the cutters is the same as that of the rotation of the stick to be turned, so that at their opposing contacts their surfaces will run in contrary directions.

Patent No. 324,847, dated August 25,1885.

(No model.)

D is the table, having a reciprocatory motion toward and from the cutters and running on the ways d, as shown. On this table are mounted the centers d and d", which hold the stick to be turned, a comparatively slow rotation being communicated to the stick thus held by the gear (1 011 end of shaft (1*, carrying the headcenter,meshing into bevel-gear d on the overhung shaft (1. Power is communicated to this shaftby a belt, cl, from the main shaft or arbor to a pulley, (I on the shaft (1 and thence by belt of to pulley d. A loose pulley, d, is also arranged on shaft (1, so that when the table is drawn away from the cutters the shaft (1, which is mounted on the table and slides longitudinally in its bearings, will, on moving with the table, throw the belt (1 to the loose pulley, and thus the rotation of the wooden stick cease. \Vhen the table is carried toward the cutters, the said belt is thrown onto the live pulley d, and the wooden stick consequently rotated. The belt d" is an angle-belt, as shown plainly in Fig. 4.

I will now describe my improvements.

E is a shaft mounted to rock in bearings e, mounted on the 1nachine-frame. From this shaft, and fixed to it, extend arms 0 up to the forward edge of thetable, where their extremities are pivoted, as at c", to suitable lugs, e, fixed on the table. From one end of the shaft, on the outside of the machine, extends the crank-arm e, the extremity of which is united by a connecting-rod, 6 to a foot-lever or treadle, c", pivoted to the frame at 6 By means of these devices the operator is enabled, by pressing upon the lever c with his foot, to carry the table toward the cutters, and thus accomplish the turning of the stick, having his hands free to handle the sticks successively and rapidly.

F is the tail stock, and is supported to slide horizontally on a bar, f, which is adjustably secured to the table D; and it is moved and adjusted on said bar by means of a headed screw, f, which passes freely through the lug f 2 on the said bar and into a screw-threaded hole in a lug, f, on the tail piece. The said bar is secured to the table by means of bolts f f, which pass through. ears f f ,projecting laterally from the said bar, and through the slot f in the table, thus permitting the longitudinal adjustment of the tail'stock on the table. The spindle G, carrying the center (1 slides in ways in the tail-stock, and is moved by means of an eccentric, G, journaled in an arm, 9, projecting from said stock, the said eccentric working in an elongated opening, 9, in the outer end of said spindle.

G is an arm connected with said eccentric, and provided with a weight, 9 at'its extremity. This arm is so arranged that when it is raised upward it rotates the eccentric and slides the spindle away from the opposite center, (1, and when it is lowered reversely rotates the eccentric and slides the spindle toward the opposite center.

To remove a turned stick and insert a fresh one, the operator has therefore pnly to raise the weighted arm G and then let it fall, the weight operating to hold the spindle against the end of the stick, and thus to maintain it during the turning between the centers d and d.

At H, Fig. 3, is indicated a hood or dust and shaving guard, arranged above and be hind the cutters.

What I claim as my invention,and desire to secure by Letters Patent, is

1. In a wood-turning machine having the arbor B, carrying cutters O, and table D, working on ways (I and supporting the centers d and (Z and provided with the bevelgears d and (P, the shaft (1, with its live pulley d and loose pulley d, the combination, with said table, of the rock-shaft E, arms e, pivoted to lugs 0 crank-arm 6, rod 0 and foot-lever e, as and for the purpose specified.

2. In a wood-turning machine having the arborB, carrying cutters O, and table D, supporting the centering-spindles and having a forward and rearward movement on the machine-frame, the combination, with the said table, of the tail-stock F, supported to slide horizontally on the bar f, and which is adjustably secured to the table in slot 1' therein by means of bolts f and f working in ears f and f respectively, together with the spindle G, the eccentric G, journaled in arm g, and the weighted arm G as and for the purpose set forth.
